4L65E Overhaul Kit 1993-2003, new and ready to install. Fits the 4L65E. Ships fast from the USA.
This is the budget sealing kit for the early years of GM's electronic four-speed. The listing covers 1993-2003, which reaches back before the heavy-duty 4L65E existed and takes in the 4L60E it grew from, so it is aimed at owners of 1990s and early 2000s C/K and GMT800 pickups, Tahoes, Suburbans, Blazers, Camaros and similar rear-drive GM vehicles who need to reseal a tired unit. If you are rebuilding on a tight budget and the hard parts are still good, this is where the job starts.
An overhaul kit replaces the soft parts that age out: the pan, pump and valve body gaskets, the lip seals on the clutch pistons, the shaft sealing rings and the O-rings at the servo, accumulators and electrical connector. In a 1993-2003 unit those parts are now decades old and many have hardened from heat. Once a piston seal or sealing ring loses its grip, the clutch it feeds applies slowly or not at all, and that shows up first as a delay into gear and a soft shift, long before anything breaks.
Not every delayed engagement on these years is worn seals. GM dealer service bulletin 67-71-48 covered 1995-96 4L60-E units built before April 29, 1996 that engaged late after sitting more than 48 hours, and traced it to fluid draining out of the torque converter; the factory fix was a revised pump cover with a new TCC signal valve, not a reseal. So check the build date on your unit's ID plate and note whether the delay only happens after a long sit. A unit that slips hot or leaks from several places is a better candidate for this kit. The 4L65E pump failure guide explains how pump wear and low line pressure show up, and the Silverado 1500 problems guide lists what owners of these trucks report most.
The listing covers 1993-2003. Across those eleven years GM changed pan, pump and case details more than once, and the true 4L65E only appears near the end of the range in 6.0L trucks. Lay the gaskets in the product photos next to your old ones, check that the case connector O-ring matches, or send us your year and VIN and we will confirm before it ships. A 1997 or later unit can also use the 1997-2003 overhaul kit. See the full 4L65E and 4L60E parts collection for hard parts.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. The 4L65E is a heavy-duty development of the 4L60E that appeared in the early 2000s. This kit's 1993-2003 range covers the shared 4L60E family, so it fits earlier 4L60E units as well as early 4L65E trucks.
An overhaul kit is the gaskets, seals, sealing rings and O-rings. A master kit adds frictions and steels, and often a filter. At this price, plan on buying clutches separately if yours are burnt.
Maybe not. GM bulletin 67-71-48 traced that exact complaint on 1995-96 4L60-E units built before April 29, 1996 to converter drain-back and fixed it with a revised pump cover.
No. Install a new filter and seal any time the transmission is apart; old clutch debris in the filter will contaminate the rebuilt unit.
Compare the gaskets in the product photos to your old ones and check the connector O-ring, or send us the year and VIN before ordering.
